Carbon footprint of wheat-summer direct-seeding peanut planting system in Shandong Province, China
摘要
Abstract
Clarifying the carbon emissions in wheat-summer direct-seeding peanut planting (W-P) system could help realize the synergistic effects of high yield and low carbon emissions. Based on whole life cycle method,we constructed a carbon footprint model to calculate the carbon emissions of W-P system. We found that the net income of W-P system was 71.2％-88.3％ higher than that of wheat-maize rotation (W-M) system. The carbon emissions per unit area under W-P system was6977.9-8018.5 kg·hm-2,being 6.2％ higher than that of W-M system. The carbon emission of per net income under W-P system was 0.23-0.28 kg CO2-eq·yuan-1,which was 37.4％-44.1％ lower than that of W-M system. Combining the net income and carbon emissions of per net income,W-P system could achieve synergistic effects of high yield and low carbon emissions,which would fulfill the targets of agricultural supply-side structural reform with optimizing supply,enhancing quality and efficiency,and increasing income of peasants.关键词
